IMPROVEMENT IN THE CONSTRUCTION OF SAFES.

The Sched/ale referred to in these Letters Patent and making part o! the same To all whom it 'ma/y conce/rn:

Be it known that I, T. J. SULLLVAN, of Albany, in the county of Albany, and State of New York, have invented a certain new and useful Improvement in the Construction of'Safes; and I do 'hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making part of this specification.

Figure l is a horizontal section of my improved safe.

Figure 2, a perspective view of the skeleton, re-

moved from place.

B B B B represent angle-plates, forming a continu- -ous and connected skeleton, of cubic form, fitting closely inside the outer plating, and fitting tlrangles, as clearly shown.

C C C O represent corner-pieces, ittinginside the corners of the angle-irons.

4The parts, thus arranged, are united by riveting the outer plates to the angle-irons, and then passing screws, a c, through the plating into the corner-pieces, whfereby the parts are closely clamped, as clearly shown in g. l.

The screw-holes are simply countersunk in the outer plates sufficiently to receive the screw-heads, (which have no slots,) and the remainder, all the way through, are tapped or threaded, and nuts, l) I), are attached to the screws on the inside.

In fire-proof work, theordinary inner lining is applied, and the intervening space filled with cement, or

other material. In this case, the back plate of the safe is not applied till the iilling is complete, andl is then attached to the angle-irons by screws instead of rivets, as before described.

By this construction, I avoid the heavy, forged, wrought-iron hoops that arel ordinarily appliedoutside of safes, which are not only expensive, but are easily torn off by burglars with suitable tools.

I substitute iu place a perfectly-smooth outside, on which no hold can be got by tools. The screw-heads, being dressed down with the surface, and having no slots, and being painted over, are not easily discovered; and, even if found, being made of steel, and threaded through, cannot be drilled out or turned loose. Besides, the riveting of the plates to the anglearms is an effectual safeguard.

In addition to the above, the angle-irons, united in skeleton-form, iittiug exactly the interior ofthe safe, and st'iiiened by the corner-pieces C, make a most substantial and eective brace or support to the outer plating of thc safe, si nce every side is stayed all around.

By this simple construction, lunch labor and many dollars are saved in every safe, while the work is really stronger and more enduring than in any other with which I am acquainted.

I am aware that angle-irons and corner-pieces have before been used in various relations, serving as attachments or stays simply. Such, in themselves, I do not claim. But I am not aware that such parts have ever been united in skeleton-form to produce a complete frame.

What 'I claim as my invention, and desire to secure by Letters Patent, is

The special construction of the safe, as herein set forth, viz, with smooth sides A A, united by screws and rivets to au interior skeleton made of angle-irons B B and corner-plates C C, the whole arranged as described, and for the purpose specified.

In witness whereof,Il1avc hereunto signed my name, in the presence of two subscribing witnesses.
